Solve the problem.In 1995 the population of a certain city was 23,000. Since then, the population has been growing at the rate of 300 people per year. Is this an example of linear or exponential growth? Find a function f that computes the population x years after 1995.
A. Linear; f(x) = 23,000x + 300 B. Exponential; f(x) = 23,000(1.03)x C. Exponential; f(x) = 23,000(300)x D. Linear; f(x) = 300x + 23,000
